Coombs says Manning isn't pleading guilty to the offenses charged by the government. Rather, he's offering to plead to less serious offenses that make up part of some of the more serious charges against him.

Even if the court accepts the offer, military prosecutors could still try to prove Manning guilty of the more serious charges. They include aiding the enemy, punishable by life imprisonment.

Coombs also says Manning has elected to be tried by a military judge, not a jury, in February.
